Girls as young as ten are among more than 200,000 children wed to adults in the United States in just the past 15 years, as — despite minimum requirements a person reach the age of 18, or legal adulthood, nationally — a smattering of locations have preserved loopholes legally permitting child marriage.

Alarmingly, the number of children married away to fully mature adults could be much higher than the already-startling number — ten states provide only fragmentary statistics, or none at all.

And the loopholes don’t exist solely in theory — adults across the U.S. have actively opportuned the law to marry kids — even amid a decline in the number of marriages, overall.

To wit, three 10-year-old girls and an 11-year-old boy were among the hundreds of thousands of children and minors the system somehow permitted adults to lock into marriage — despite their bodies and minds not yet being fully developed.

“At least 207,468 minors married in the US between 2000 and 2015, according to data compiled by Unchained At Last, a group campaigning to abolish child marriage, and investigative documentary series Frontline,”The Independentreports.

Exemptions from the national marriage minimum age of 18 exist for circumstances like pregnancy and parental consent — in every state in the country.

However, record-keeping remains inconsistent across the country, and details regarding the nature of child marriages — if unintended pregnancy made the union tenable, for instance — usually aren’t included.

Indeed, New Jersey Governor Chris Christie — citing conditions such as religious customs — bore the brunt of furious criticism recently for refusing to sign into law restrictions barring children under the age of 18 from tying the knot or entering a civil unions.

“I agree that protecting the wellbeing, dignity, and freedom of minors is vital,” Christie placated an irate populace, upon refusing to codify the law in early May, “but the severe bar this bill creates is not necessary to address the concerns voiced by the bill’s proponents and does not comport with the sensibilities and, in some cases, the religious customs, of the people of this State.”

Unchained At Last Founder and Executive Director Fraidy Reiss — herself, an albeit older victim of forced marriage — toldFrontline that, upon first obtaining child marriage statistics for New Jersey, where her organization is based,

“I got that spreadsheet from the state health department, I was literally shaking.”

Data for the state revealed just under 3,500 youth — largely 16- and 17-year-olds — wed adults between 1995 and 2012.

“That number was so much higher than I had thought it would be,” Reiss told the PBS program. “Then, the fact that the children were as young as 13 and the fact that it was mostly girls married to adult men.”

Across the U.S., insufficient data still show the number of marriages involving minors and children dropped by 61 percent in the decade between 2000 and 2010 — but even that figure could be wildly inaccurate without further information readily available.

Lest doubt take root, these figures haven’t been bloated by an excess of youth permitted to marry other youth — fully 86 percent of marriages analyzed with available data involved adults wedding kids under 18.

“The youngest children to marry were three 10-year-old girls in Tennessee in 2001, who were married to men ages 24, 25 and 31, according to state data. The youngest groom was an 11-year-old boy, also in Tennessee, who married a 27-year-old woman in 2006.

“Children as young as 12 were granted marriage licenses in Alaska, Louisiana, South Carolina, and Tennessee.

“Thirteen-year-olds were given the green light to marry in Alabama, Florida, Idaho, Kentucky, Louisiana, Mississippi, Missouri, New Hampshire, New Jersey, New Mexico, South Carolina, Tennessee, Texas, and Washington.”

Around the United States, adults — as old as the 74-year-old Alabama man, whose bride was six decades his junior — ostensibly committed to lifetime relationships with three 10-year-olds, two 11-year-olds, ten 12-year-olds, fifty-one 13-year-olds, and 985 children aged 14.

Of course, individual states’ legal loopholes don’t necessarily jibe with federal mandates pertaining to marriageable age — not to mention the gross breach of social mores and protections for children.

Frontline suggests this odd and astonishing discrepancy — if not outright hypocrisy — leaves cavernous gaps in consistency of law:

“Most states set the age of sexual consent between 16 and 18. A person can be charged with sexual abuse or statutory rape for having sex with a minor. Yet, we found numerous examples of children who were given marriage licenses before they could legally consent to sex. These marriages were almost always approved by court clerks and judges.”
